bsvd is a full-node Bitcoin (BSV) implementation written in Go.

The default options are sane for most users.  This means bsvd will work 'out of
the box' for most users.  However, there are also a wide variety of flags that
can be used to control it.

The following section provides a usage overview which enumerates the flags.  An
interesting point to note is that the long form of all of these options
(except -C) can be specified in a configuration file that is automatically
parsed when bsvd starts up.  By default, the configuration file is located at
~/.bsvd/bsvd.conf on POSIX-style operating systems and %LOCALAPPDATA%\bsvd\bsvd.conf
on Windows.  The -C (--configfile) flag, as shown below, can be used to override
this location.

Usage:
